Cassini bounced radio waves off Titan’s three largest seas and found their open surfaces mirror-smooth, with roughness no greater than 3.3 millimetres RMS, while rougher estuaries hinted that methane-rich rivers were entering more ethane-rich seas

Source Summary

Four Cassini bistatic radar flybys found millimetre-scale roughness across Titan's open seas and rougher estuaries consistent with methane-rich inflow meeting more ethane-rich liquid.
